Description

Technical Field

[0001] The present invention relates to the field of municipal gardens, and more particularly to a tree insecticide device for municipal gardens and a method for using the device. Background Art

[0002] Municipal administration refers to the various administrative work of the city, and also refers to market trade affairs. Urban management work includes industry, commerce, transportation, public security, culture and education, environment, health, infrastructure, etc. Garden refers to a specific cultivated natural environment and recreational area. The beautiful natural environment and recreational area created by using engineering technology and artistic means in a certain area through transforming the terrain, planting trees and flowers, building buildings and arranging garden paths is called a garden. Classical garden architecture is unique in traditional Chinese architecture and has made great achievements. The park composed of green plants, artificial lakes and runways in modern cities is a kind of municipal garden. In order to increase the green area in modern cities, it is necessary to carry out pest control and pest control on garden trees to maintain the trees and reduce the death of trees due to insect pests.

[0003] There are three main ways to kill insects and pests on trees. They are to place insect attractants to kill insects, spray insects with drugs, or whitewash trees to protect them. The three methods can be used independently or in combination with each other. Whitewashing trees means that workers brush a layer of white liquid on the trunks. The main advantages of whitewashing trees are: sterilization, prevention of bacterial infection, and accelerated wound healing; insecticide and insect prevention, killing eggs and pests in the bark.

[0004] Existing protective measures for killing insects and pests on trees can generally only kill pests and their eggs on the surface of trees, but there is no good insecticide effect on pests in the soil below the tree planting. In addition, pests and eggs in the soil have a more important impact on the growth of tree roots. Artificial excavation of the soil surface is inefficient. Therefore, how to propose an insecticide device that can assist in disinfecting pests in the soil around trees and reduce the survival rate of pests and eggs is particularly important. In view of this, we propose a tree insecticide device for municipal gardens. Summary of the invention

[0013] S1. Pest control and detection: Municipal garden trees are tested by manual and machine detection to classify the trees. Pests and eggs in the soil are classified, and the others are classified into one category;

[0014] S2, the setting of pest control agents, the whitewashing agent is mixed with clean water and white lime, and the soil insecticide is stored separately;

[0015] S3, machine pest control,

[0016] If only the municipal garden trees are to be whitewashed, firstly, a mixture of clean water and white lime is placed in the mixing box. The dosing conveyor includes a quantitative dosing device and a delivery pump. At this time, the output end of the mixing box is connected to the input end of the delivery pump through a pipeline, and the output end of the delivery pump is connected to the connecting pipe. Then, the pipeline at the output end of the mixing box is directly connected to the input end of the delivery pump at the rear end of one of the dosing conveyors. Then, the mounting bolts of the connecting frame are loosened, and the combined structure, cylinder, spraying mechanism, and plowing mechanism are rotated 180 degrees and re-installed on the connecting frame through bolts, so that the spraying mechanism is located on the hydraulic lifting frame. Then, the insecticide is installed on the external driving vehicle through the traction mounting buckle, and then the insecticide is moved to the driving vehicle and the driving device. Move to the place where the garden trees are whitewashed, and with manual assistance, the sub-arc-shaped arms are rotated and unfolded to fit the combined structure on the outer wall of the garden trees. Then, the sub-arc-shaped arms are rotated and closed manually, and the sub-arc-shaped arms are fixed with plug-in fittings and bolts to form a closed circle. The motor at the upper end of the mixing box is turned on to drive the stirring rod inside the body to stir. Then, the spraying mechanism is lowered to the lower end of the garden trees through the hydraulic lifting frame, and the white lime water is sprayed on the tree trunks through the delivery pump and the lime spray head, and the hydraulic lifting frame is used to spray to more than 1.4 meters of the tree trunks, so as to effectively prevent the occurrence of insect pests on the tree trunks, and to maintain and protect the garden trees. In the spraying process, the insecticide can be driven by the driving vehicle to perform a small rotation movement to avoid uneven spraying of the tree trunks.

[0017] For example, if the soil around garden trees is to be disinfected, first, the dosing conveyor includes a quantitative dosing device and a delivery pump.

Then, the insecticide is moved to the whitewashing garden trees through the driving vehicle and the driving device. With manual assistance, the sub-arc arm is rotated and unfolded to fit the combined structure on the garden trees. The outer wall of the wood is then manually rotated and closed by the sub-arc arms, and the sub-arc arms are fixed with plug-in accessories and bolts to form a closed circle. The mounting frame is pushed by a cylinder to rotate and adjust the required plowing area of ​​the soil. The cylindrical plow blade is then driven by the drive motor to rotate to plow the soil around the garden trees.
